I received the Nissan Sentra lowering springs but have racked up the Leaf to inspect / install yet. At first glance it is clear that two of the four Sentra springs will probably fit and two will not. The leaf has a relatively large diameter spring coil front and back - about 6 inches diameter coils. The 2012 Sentra spring set has one large dia spring that looks good and one very small dia spring that is about 3 inch dia coils. Looks like the Sentra spring set yields one set of usable springs. I have to look more closely to see if the large dia Sentra springs are best suited to the leaf front or back.

Pretty sure its been mentioned somewhere else in this thread but Megan racing (http://www.meganracing.com" onclick="window.open(this.href);return false;) sells a Nissan Leaf coilover kit. 32 way dampening adjustability and height adjustable from stock to about 2-3/4" lower than stock. I have it installed on my Leaf if you want any other details.

I've owned performance cars for years so I'm used to having a much wider selection of aftermarket performance parts available than are marketed for the Leaf. Given that many Nissans are autocrossed and tracked, I'd really like to know if there are any off-the-shelf shocks from Bilstein or Koni (etc.) that would work on a Leaf.

Do you still have your stock suspension parts around? Documenting the stock Leaf spring rates and dimensions would be helpful too so that we have a baseline for experimenting with aftermarket springs.

If I have read this thread correctly I think the problem would be the combo of kits (front Sentra and rear Altima) you would have to buy to try it and seems not worth messing with different shocks to get the correct dampening in the rear. I’m looking into the Megan Coils in the future and play with that dampening setting
